Extremely striking use of colors and contrast - its one of the basics I know constantly challenges artists throughout their own lives nad yet you've also managed to use it to tell a story from corner to corner of this piece with seamless transition - my primary criticism is that the lighting in the very back, stretching left and down into the top left part of the shadow/darker area is too matte, it falls flat compared to the other half of the picture, from the chinese lanterns (esp blue), the cart, the flowers, the sunbeams, birds and alley gate, which are stunning and striking, full of depth and emotion.
Also, because its seamless, it may be a strength of this picture, but it also feels as though you've captured different times of the day, night, midday and morning in these vivid areas. I don't know if that's a good thing or not, but I like it in the way you've done it. There's potential here to be a little less cartoonish and very vibrant. I'd love to see it retouched up in the future, just to see what it would look like.
